Abstract :
The goal of this analysis is the separation of artificial sound from the ambient or background soundscape in real-time via singular value decomposition of a 3×3 covariance matrix obtained from the set of vector measurements sourced from a particle velocity sensor. The summary noise power is then computed for each octave band, and this is used to detect the presence of artificial, polluting sound sources.
